This paper examines the potential impact of artificial intelligence (A.I.) on economic growth. We model A.I. as the latest form of automation, a broader process dating back more than 200 years. Electricity, internal combustion engines, and semiconductors facilitated automation in the last century, but A.I. now seems poised to automate many tasks once thought to be out of reach, from driving car...

Reconsideration of a Tour de France cyclist.

IN 2005, THIS AUTHOR PUBLISHED a paper in the Journal of Applied Physiology that described physiological changes that occurred in a Tour de France cyclist as he matured from 21 to 28 years of age during the period of 1992 to 1999 (2). This cyclist has recently admitted to using performance-enhancing drugs. That leads us to wonder if any of the physiological changes reported in the 2005 paper mi...

Dynamical (super)symmetries of monopoles and vortices (1) Abstract. The dynamical (super)symmetries for various monopole systems are reviewed. For a Dirac monopole, no smooth Runge-Lenz vector can exist; there is, however, a spectrum-generating conformal o(2, 1) dynamical symmetry that extends into osp(1/1) or osp(1/2) for spin 1/2 particles. Self-dual 't Hooft-Polyakov-type monopoles admit an ...
